VeilNebFrm2 RoughLRGB ForSharing
I'm looking for honest & constructive feedback :-)
I haven't done that many LRGB images before, so I am not 100% confident with my processing skills, accurate colour balance, etc etc. For starters, I am getting a brownish colour just above the "Witches Broom" and also to the right of Pickering's Triangle. Have I captured dust in those regions, or have I just a done poor job managing the background colour balance etc? ;-)
IMAGE DETAILS:
Luminance Exposures: 6x10min,
RGB Exposures: for each colour, 6x5min Binned 2x2
Telescope: Takahashi FSQED Camera:
STL11000M with Astrodon Trubalance filters
Location: New Mexico Skies, near Cloudcroft, New Mexico, USA
Conditions: Very dark skies, good transparency, and very good seeing.
Processing: Captured, stacked, combined, DDP, and some curves using MaximDL5Pro, aligned using Registar, LRGB processing via Photoshop CS3 and Noel Carboni's Astrotools, gradient removal using Gradient Xterminator, and Noise removal using Noise Ninja plug-in for PS CS3.
I am looking forward to your input! :-)

Thanks Trevor and Starhopper. All great info and feedback!! :-)
FYI, I do have narrowband data too, but I like seeing what the LRGB looks like on its own. Also, I am still learning how to integrate NB data into LRGB data, and after reading Debra Ceravolo's excellent article in the Dec. S&T, I have all sorts of new things to 'process' in my mind too! :-)
How do I send an image to "Reprocess My Image"? What format should the data have?
Thanks everyone!

Hey where did my comment go?
Anyways, Derek, Hopp already gave you constructive feedback, and he's a good one to get it from, all I have left is the honest type...this s sweet image. But please take his advice and throw it in Reprocess My Image....I would love to take a crack at it!

Nice look, you don't see the upper veil region too often. If you're adding more time, a set of Ha subs always works great in this area. Really like the color (particularly the stars). Good work, Marc

Hey Starhopper. Thanks very much for the pointers! I am definitely no expert with processing and only know some of the functions in Photoshop, so I appreciate you sharing your wisdom! :-)
BTW, I must apologize, as that 100minutes was a typo....I can't believe I missed that error! (I'm saying this with an embarrassed grin) The luminance was 6x10minutes for a total of 1 hour of luminance. Sorry! :-( Having said that, I will confirm that the skies at New Mexico Skies are some of the darkest in North America.
I'm doing Google searches for other shots of this field to see if I can find other long exposure RGB or LRGB images that may show up something to confirm what I have. Most images I've found have osome narrow-band data in there, so the background is often processed to be black. I also plan to take more exposures to see if those brownish areas disappear or become more obvious. Stay tuned! :-)
